0.3x+3.4=y
Swap sides so that all variable terms are on the left hand side.
0.3x=y-3.4
Subtract 3.4 from both sides.
\frac{0.3x}{0.3}=\frac{y-3.4}{0.3}
Divide both sides of the equation by 0.3, which is the same as multiplying both sides by the reciprocal of the fraction.
x=\frac{y-3.4}{0.3}
Dividing by 0.3 undoes the multiplication by 0.3.
x=\frac{10y-34}{3}
Divide y-3.4 by 0.3 by multiplying y-3.4 by the reciprocal of 0.3.
